An overview on behavioral genetics
By: Wendy R.
Trying to define behavioral genetics can be difficult. In simple terms, it is the study of genetics in relation to the outward behavior of an organism that is seen. So in other words, it is the study of the hereditary factors of behavior. Included...

Although it has long been known that genetic errors such as Down's syndrome and phenylketonuria often impact negatively on intelligence as well, the extent to which normal genes play a role in determining human intelligence is much less clear. To determine what, if any, role...

Sperm and egg unite; it is the symbiosis of a new life, the beginning of a new being. Paternal and maternal progenitor beings have each contributed a blueprint containing one half of their own genetic recipe. In the case of humans, 23 chromosomes each will...
Gene expression explained
By: Michelle Mak
Gene expression is the process of protein formation. Proteins are the molecules that are responsible for enabling us to live. They carry out majority of the processes that are important for life, as they include enzymes, transcription factors and the various cell machinery. Indeed...
The differences between RNA and DNA
By: Alicia M Prater PhD
RNA and DNA are two types of nucleic acids. The differences between these two molecules involve their chemical composition and, sometimes, their structure. RNA stands for ribonucleic acid, and DNA stands for deoxyribonucleic acid. As the names imply, one difference between these two molecules is...
DNA replication errors
By: Elisa Sala
DNA is a double stranded helix, constituted by four nucleic bases: adenine, thymidine, cytosine and guanine. Two strands of double helix are linked through hydrogen bonds, weak chemical bonds between adenine- thymidine and cytosine- guanine. These bonds guarantee to keep constant the distance between two...
Alcoholism and genetics
By: Nadine Riggs
Alcoholism and its genetic component has yet to be determined, it is still under study by the Medical and Psychiatric societies. Is the child of an alcoholic more likely to become an alcoholic, then the child of a non-alcoholic parent? It does seem to have...
Genetics science projects for high school students
By: Alicia M Prater PhD
High school level genetics is usually a study of the basics of genetic theory and DNA structure. Though college level classes have the facilities and resources to conduct more advanced, and yet still somewhat basic, projects, high school resources would be more general, and require...
Difference between dominant and recessive genes
By: Magda DH
Difference between dominant and recessive genes Strictly speaking, there is no such a thing as a dominant or recessive gene. A gene is a section of the DNA that encodes a particular instruction, or a set of overlapping instructions: a basic unit of inheritance. A...
What are gene alleles?
By: Magda DH
Alleles are different versions of the same gene. In popular every day usage, when people talk of "a gene for something" they often mean what is correctly called "allele". There is no gene for blue eyes, for example, or gene for wrinkled pea seeds: what...
